Discover how ERC-6551 can deliver the promise of interoperable NFT and cross-game gameplay.

ERC-721 has given rise to various non-fungible token (NFT) applications. However, ERC-721 has two main limitations. One of ERC-721's limitations is that it is unable to own assets. Another of ERC-721's limitations is that it is incompatible with other on-chain assets. The solution is ERC-6551’s token bound accounts (TBAs).

Using TBAs, ERC-6551 is transforming Web3 gaming with customizable NFTs. The interoperability of these NFTs allows for cross-game gameplay. In addition, ERC-6551's TBAs also function as smart contract accounts. These accounts can own Web3 gaming assets and verify the transaction history of these assets.

• Interoperable NFTs

ERC-6551's TBAs are compatible with almost all existing on-chain and off-chain infrastructure. This compatibility element enables ERC-6551's TBAs to support interoperable NFTs for cross-game gameplay. For example, suppose there is a Pokemon Web3 game with Pokemon NFTs and a Digimon Web3 game with Digimon NFTs. ERC-6551's TBAs enable the NFTs of the Pokemon Web3 game to be used in the Digimon Web3 game and vice versa. This element allows for Pokemon vs. Digimon cross-game gameplay battles using Pokemon NFTs and Digimon NFTs.

• Assets Ownership

ERC-6551's TBAs can own any type of on-chain assets. This asset ownership feature enables ERC-6551's TBAs to be used as customizable inventories for gaming NFTs. For example, suppose there is a Pokemon Web3 game that has various NFT assets such as PokeBall, PokeDex, and PokeRadar. ERC-6551's TBAs would function as a Trainer's Bag to store these NFTs as contents in the Bag. The ownership of the NFTs in its customizable inventory will be transferred when the Trainer's Bag is sold. This feature allows for on-chain ownership of gaming NFTs to improve user experience.

• Credentials Verification

ERC-6551's TBAs can track and store transactions of on-chain assets. This transaction history recording function enables ERC-6551's TBAs to verify the past activities and unlocked achievements of gaming NFTs. For example, suppose there is a Pokemon Web3 game with League achievements in the form of Gym Badges NFTs. ERC-6551's TBAs could track and store information on League battle records in Gym Badges NFTs. This function allows for on-chain verification of the credentials of Web3 gamers to improve user motivation.

The on-chain verification function of ERC-6551's TBAs improves the motivation of gamers. In this manner, ERC-6551 is a game changer for Web3 gaming NFTs.
